EBIKELING Universal Torque Arm Conversion Kits for Electric Bicycle, EBike Front or Rear Hub Motors and Mid Drive e-Bike Tool for Maintenance, 6 pc Ebike Accessories

I installed one on each side of the forks on my father's adult e-tricycle with 250w hub motor. Curiously, his bike did not come with them. After about 3-4 months of use, the torque from them motor opened the cradle end of the forks allowing the shaft to spin. I did a little internet research and found these torque arms on Amazon. Package was delivered quickly and was easy to install (after watching a YouTube video on installation). His forks use small diameter tubing and the provided clamp was made for fairly large tubing. So, I used two smaller clamps that I had in my garage. The larger ones would have worked, but I would have had to cut the excess length of strap from the clamp. Overall, I'm very satisfied and my father is pleased to be able to ride his bike around the park. At 92 years old, the motorized tricycle is a real blessing.

I works perfectly to keep the motor from stripping my front forks from rounding out from torque of motor.

Overall this is a well-made and versatile torque arm. The slot in the lower part of the arm is wide enough to use on the cable side of a front wheel ebike motor installation as well as on the non-power side, depending on personal preferences and your fork shape. (Although a torque arm is not strictly necessary with a 250 watt front wheel motor I thought with my aluminum fork it would be a helpful safety feature.) I downgraded the product from 5 to 4 because the hose clamp supplied to secure the torque arm to the fork is of very poor quality. It was very difficult to tighten it. I ended up using a better quality hose clamp of my own.

Unlike other reviews mine is thick metal and perfect tight fit. That is the way it is with anything made in China because they do not have patten pending like the USA and quality varies. The only issue was missing a little washer and the hose clamp is way too large but able to make it work. It was just time consuming tightening it down that much and the excess doesn't look the best. But over all I give it 5 stars.

Doesn’t work with my frame on either the gear or non-gear side.In the optimal placement position, the inner nut (even without using lock washer) is too prominent and abuts the frame.If it is placed in a different position, to allow the holding bolt to not strike the frame, the other arm either interferes with the nut holding the rear drive wheel on or leaves the slot for the hose clamp in a sub optimal position.I’m going to get some washers to offset the bracket to allow for clearance of the nut, but the farther the bracket is from the frame, the less effective both for the torque limiting effect and this may also reduce the number of threads for the main nut holding the drive wheel on. Sigh.This, this arm isn’t right for my frame (and there’s not really a way to determine this up front without buying and trying), but the alternative, to make my own, is even less appealing so time to just MacGyver it to make it work, but only gets 3 stars.Hard to make things universal, but pretty frustrating to buy something that doesn’t fit.

Need it to keep the axile from spinning

Good quality very thick the clamp is way too and not the best quality.

Didn't use it at first and damaged my front drop outs and was about to danger my rear ones as well but with this on it's all good. No issues in over two months and 1000+ miles! Just make sure you find a good way to mount it so it won't move at all because with this torque arm it can be a bit tricky.Also I have a steel frame...if you have aluminum is recommend using these torque arms even for just 500w.....yeah....

I bought this product for my friend. He is very satisfied with it. Really fast and easy delivery.

Not stainless steel. the security given at 30 miles a hour priceless. not recommended. slower safer is better.

Be aware the "coloured" arms are just spray painted, they are not a coloured metal alloy. Works as it shouldI found the clamps too large for my fork setup so I had to go to hardware store to get smaller ones. This does the job.

High quality strong metal. Worth every penny. Thinking of buying another one, for the rear one....
